I'll liked to build the six-key GKOS

Is there a more detail part list, e.g. switch part number..

So I can just order the parts and wire it up myself.

Hi Terence,

I wrote a blog post about my gkos keyboard:
http://blog.ulrichard.ch/?p=1196

The parts are essentially these:
http://www.dx.com/p/6-key-usb-handle-hid-keyboard-173cm-cable-70892#.VIb4G13cI_s (sold out, too bad)
http://www.play-zone.ch/en/adafruit-bluefruit-ez-key-bluetooth-hid-kb-controller-v1-1.html
http://www.dx.com/p/aaron-1-atmega328-pu-atmel-microcontroller-chip-for-uno-r3-uno-328-2pcs-267118#.VIb4t13cI_s
The crystal and capacitors are the standard ones used with the AtMega's.
If I remember correctly 20Mhz and 22pF.
The LiPo battery is from a broken micro quadrocompter.
And some standard stripboard, headers and a switch.

The arduino code is straight from the GKOS page. It is missing some
special handling for special characters, but I had no need for them so
far.

Feel free to ask if you need more information.

Hi, Richard

Thanks for the info, but the mechanical design of the device shown in this video is more what I am interested in.
